A bit of a nitpick, but Yin Kagkai was not involved in this patch, I 
wrote it myself ...

... the commenting syslog thing was an unrelated patch, maybe various 
commits were squashed?

When I tried out the patch, I added a local copy of 
https://patch-diff.githubusercontent.com/raw/ajraymond/restartd/pull/8.patch 
to the list of patches and "guix build" succeeded, there was no need to 
squash things.
